One of the most common solutions to the problem of feeding a three-phase induction motor from a single-phase line is using AC/DC/AC converter. An AC/DC/AC converter is composed by two stages, rectifying and inverting. The rectifying stage, or front-end, is generally implemented using a diode bridge rectifier or a boost rectifier. This paper evaluates the performance of a SEPIC (Single Ended Primary...
Traditional rectifiers such as the half-wave and full-wave rectifiers have been the only configuration used in resonant inductive links. Despite their popularity, their input current contains a large amount of harmonics which makes them incompatible with resonant inductive links especially those driven by a Class D or Class E resonant inverter. This paper presents a half-wave Class D voltage-switching...
This paper is concerned with the design and simulation of a pulse width modulation (PWM) rectifier for three-phase Permanent Magnetic motor drive. Based on the mathematical model of PWM rectifier, the dual-close-loop engineering design with decoupled feed-forward control is applied in the 3-phase voltage source rectifier. The objective to be reached is to realize unity power factor at the input ac...
